by reducing flow rate, you not only reduce friction but also npsh required from pump. you can also throttle pump on the outlet. for npsh calculation, you need to include vapour pressure of liquid.
Excellent presentation, one solution giving to overcome suction cavitation was to slow the pump down, this is correct but can only be done if engine driven or fitted with a variable frequency control if electric motor driven - in the case of a fixed speed driver, increasing the discharge head on the pump by throttling the discharge with a valve, or orifice plate will also reduce flow and overcome cavitation. Of course reducing speed or restricting the discharge will effect the pump performance in terms of flowrate and delivery head, now if the duty flow and head cannot be changed because of application requirements - it could mean a new pump selection is required.

Beautifully and Brilliantly explained by Mr. Pete Snow.
Thank you very much for your effort.
Great piece of info. One of the best presentation on the subject

Excellent presentation.
the video was very informative , thankyou
can you please post a video based on discharge cavitation??
Fantastic explanation!!
Wow! Excellent presentation, very detailed and easily understandable. Well done!
Wow, learn a lot in very few minutes, due to the excellent explanation. Thank you SIR.
U made it more clearer thank you
Is it possible to have some of your explanation/lecture on PDF please. Thanks again.
Excellent explanation, this has resolved my problem. Thank you
Best explanation ive seen so far..thank you sir Pete😊
Good bless you
Perfect explanation
Interesting, very helpful
Beautiful explanation
excellent explanation

This is amazing, thank you
Very well detailed and explained. Great job
wow what an explanation
Many thanks, video is full of useful informations.
Thank you.
Excellent
So useful
Why not use the implosion discovery as a benefit. I would think a certain carbonyl ceramics could make synthetic diamonds
Soo useful sir👍
